RUNNING-GEAR Fort MI vEoAns.

To all whom it may concern:

Be it known that we, JOHN M. InILmrs and ROBERT F. PHILLIPS, citizens of the United States, residing at Garrick, in -t ie county of Allegheny and State of Pennsylvania, have invented certain new and useful improvementsin Running-Gear for Nine- Cars, of which the following is a specification.

This invention has relation to running gears for mine cars and. relates in particular to the wheelsand axles of running gears in which the wheel is confined in position on the axle by means of a linch pin.

It has been found in practice that the bore of a mine car wheel rotating on a stationary axle wears out sooner at the back of the wheel, that is, at thatside of the wheel which is next to the car, than at the opposite side of the wheel. In order to obviate this uneven wear it is necessary to supply lubricatin oil more freely to the rear ent of the bore t an to the front end of the same, and this has been accomplished by closin the front end of the bore, as by a ca made integral with the wheel or an attac ied cap so that, as there is no escape for oil at the front of the wheel, all the waste oil escaping from the oil cavity of the wheel will flow between the inner end of the bore and the axle, thereby keeping this portion of the bore liberally lubricated.

The cap wheels above referred to, while they have some good features, the principal one of which has been indicated above, are objected to by some operators'for the reason that the linch pin which confinesthe wheel on the axle is concealed from view, being usually arranged within the cap or at the back of the wheel, and is liable to become worn out or broken without attractin atten tion and. to cause a serious wreck. .for this reason the wheel 111 general use at coal mines .is one with a straight bore having an axle of uniform diameter extending through the bore and a hnch pin on the outer side of thewheel and whlle t e. oil may escape at the frontof the Whel, this-form is preferred to the cap wheel, as the linch pin is plainly in sight and can be readily replaced if worn or broken.

Our invention has for its object the provision of a wheel and axle which will possess all the advantages of both the cap wheel and its axle and the ordinary wheel with the bore possess other advantageous features, while and axle of uniform diameter, and the linch pin on the outside of the wheel, and will also' -chamber 4 to the bore or eye.

ramm d March 17, 1908. a

free from the objectionable features of both these types of wheels, and in carrying our invention into effective provide a wheel having a cap with a central opening of somewhat less diameter than the bore of the wheel and an axle having its outer end reduced in diameter to form a stub-axle to fitthe central opening in the cap the reduced portion of the axle being of sufh cient length to rotrude through the opening in the cap and eyond the outer face of the cap and plerced for the reception .of a suitable linch pin or; similar device to confine the wheel on the axle.

In the accompanying drawings: Figure 1 is a vertical transverse sectional vlew of a wheel and axle constructed according to our invention and as applied to an axle-without an axle box. Fig. 2 is a top plan view of the axle shown in Fig. 1 v

The wheel shown in the drawing and embodying our improved construction is of the type known as a self-oiling wheel and isa sin- .gle piece of cast metal comprising the rim 1 the spokes 2 and the hub 3, the latter bein formed with an oil chamber 4, having an 01 inlet 5 controlled by a spring pressed valve 6.

An opening 7-extends from the oil chamber 4 to the central bore or eye 8 of'the hub and serves to permit passage of the oil from the The hub 3 is formed with" an integral cap 9 en its'outer side and this cap is formed with a centrally located hole 10 o r the reception of the end of the axle as will be presently described. The axle, designated 11-1s formed with a c e lindrical portlon 12 that fits snucgily in t e bore or eye 8 of the hub and the en 13 of the axle is reduced in diameter to such site that it'will fit the hole in the center of cap 9.; The end 13 of the axle is pierced at 14 to receive a linch pin 15 which serves to confine the wheel on the axle and a washer 16 is fitted on the end 13 of the axle between the linch pin and the end of the hub The axle 11 carries a collar 17 which fits in a socket 18 in the rear of, the-hub o1" the wheel and this form of axle is directly attached to the car without the aid of an axle box. The reduced end of the axle which'passes through the cap on the front of the wheel joins the c lindrical portion 12 by a shoulder 25 that ears against the inner surface of the cap and this shoulder, with the collar 17, divides. the end thrust and wear so that the wheel and axle will run a long time without wearing enough to decrease the gage of the car.
